Answer:
Area = 16π
Step-by-step explanation:
Area of a circle = πr^2
= 64π
= sqrt64
r = 8 because 8 × 8 is 64
Radius = 8
Now, use the circumference equation:
= 2πr
= 2π(8)
= 16π

Answer:
D. (y+1)=5(x+2)
Step-by-step explanation:
Point-slope form follows: y - y1 = m(x - x1)
Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.
m(slope)=5
y-(-1)=5(x-(-2))
y+5=5(x+2)
